This invention relates to centrifugal extractors, and aims to provide a device for extracting liquid from yarn wound in the form of cylindrlcal packages.

In order that liquid may be extracted from a wound package of yarn without disrupting the package or displacing the yarn. it is necessary that the package'should be tightly confined and then rotated about its own axis.

Since the requirement that the package be rotated about its own'axis makes it necessary to treat each individual package of yarn separately, commercial considerations make it necessary that the confining and release of the individual packages be accomplished easily and rapidly. This is not possible with the case of ordinary confining covers which must be fastened together around the yarn package and then unfastened for removal from the package.-

' "he present invention makes practicable individual extraction treatment of cylindrical packages of yarn, by providing a device by means of which each package may quickly and easily be confined and as quickly and easily released from confinement.

Other features and advantages of the invention will appear from a detailed description of a specific device embodying it, which is shown in the accompanying drawings in which: y t Fig. 1 is a view in vertical section; and Fig. 2 is a perspective view of an element of the device.

The extractor shown in the drawings has a rigid frame 10 carrying a table 11 and providing bearings for a horizontal power shaft 12 and bearings 13, 14 for a number of vertical shafts 15 driven from the power shaft 12 by beveled gears 16. Each vertical shaft 15 projects through the table 11 and extends some distance above it. On each shaft 15 above the table 11 is fixed a hollow cylindrical holder 20 open at its top. The bottom 21 of the holder 20 has a downwardly offset central portion 22 which is screwed upon a threaded portion 23 of the shaft 15 and against an enlargement 24 formed on the shaft just above the table. A look nut 25 is screwed on against the bottom of the holder.

1929. Serial No. 879,395.

An adaptor sleeve 26 fits tightly but removably over the upper portion'of the shaft 15 above the lock nut 25 and projects above the.

open end .of the holder 20.

The holder 20 and the sleeve 26 are so proportioned to the hollow cylindrical package A of the yarn to be extracted that when the package is placed in the holder its inner surface or. core A1 fits a ainst the sleeve 26, while its-outer surface 2 is tightly confined by the inner surface of the foraminous cylindrical wall 27 of the holder. Sleeves of different external diameters may be substituted for the sleeve 26 to adapt the holder for use with cylindrical yarn packages having cores of diiferent diameters.

To facilitate the insertion of a package of yarn, and to make'possible the removal of the package, each holder 20 is provided with a movable annular disk 30 having an external diameter slightly less than the internal diameter of the cylindrical wall 27, and a central hole 31 large enough to fit loosely over the sleeve 26. To the disk 30 are secured flat bars or strips 32 which are longer than the holder 20 so that handles 33 at their upper ends project above the holder when the disk lies against the bottom of the holder. The bars 32 lie close against the inner surface of the cylindrical wall 27.

When a package A of yarn is to be placed in one of the holders, it is first seated on the disk 30 with the bars 32 against its outer surface; the hole 31 in the disk and the core A of the package are then fitted over the projecting upper end of the sleeve 26 to center the disk -and package with respect to the holder 20; and the'package and disk are then pressed down until they occupy the position shown in Fig. 1. The sliding of the bars 32 against the inner surface of the wall 27 facilitates the insertion of the package, notwithstanding the tight fit between its outer surface and the cylindrical wall of the holder. 1

The friction between the inner and outer surfaces of the yarn package and the sleeve 26 15 rotates. Since the package is tightly confined, so that the yarn cannot be displaced,

holes 34 which it contains are beveled or rounded at their inner ends as shown.

The liquid which is thrown 0a through the openings in each holder is confined by a cylindrical shield 35 resting on the table 11 and provided at its bottom with openings 36 lower than the peripheral ridge 37 of the .table, so that the liquid issuing from the holes in the shield is directed into a drain 38 in the table. To protect the bearings 14 from the liquid, they are surrounded by circular ridges 39 and by circular baflies 40, and the space between the ridges 39 and baffles 40 is connected to the drain 38 by a groove 41 in the table.

Because of the high speed of the rotation used, the bearings 14 require frequent oiling. Owing to the position in which the bottoms of the holders are fixed on the shaft immediately above the table top, the bearings are not accessible. Provision is made for oilingthem without removing the holders by providing in each shaft 15 an oil duct 42 extending downward from the upper end of the shaft and then outward below the bottom of the holder through the enlargement 24, so as to direct the oil to the bearings 14.

What I claim is:

1. A device for extracting liquid from said shaft just above said bearings and a foraminous cylindrical wall surrounding the upper portion of the shaft and open at its upper end, and an adaptor sleeve fitting on the upper portion of said shaft and projecting above the upper end of said cylindrical wall. 2. A device for extracting liquid from yarn wound in the form of hollow cylindrical packages, comprising a hollow cylindrical holder closed at one end and open at the other and having a foraminous cylindrical wall adapted to confine the cylindrical surface of a package of the yarn, andv an axial member pro ecting inwardly from the closed end of the holder and extending beyond its open end to engage the core of the yarn package and center it-before it enters the holderso as to guide it into the holder.

3. A device for extracting liquid from yarn wound in the form of cylindrical packages, comprising a rotary cylindrical holder closed eaaooe at one end and open at the other and having a cylindrical wall adapted tightly to confine the cylindrical surface of a package of the yarn, said cylindrical wall containing radial holes beveled at their inner ends so as not to catch or cut the threads of a yarn package when it is moved into and out of the holder through the open end thereof. I I

4. A centrifugal extractor for yarn packages, comprising a frame providing a table containing a drain opening, an upstanding peripheral ridge on said table, a vertical shaft journalled in the frame and projecting up through the table, a bearing for said shaft in the table, a holder fixed on said shaft above the table and having a foraminous cylindrical wall to confine a package of the yarn, a cylindrical shield surrounding said cylindrical wall and having at its bottom openings of less height than the peripheral ridge of the table, a circular baffle within said shield surrounding the bottom of said holder, and an upstanding circular ridge on the table within said baffle surrounding said bearing, the table containing a groove extending from the area between said baflie and said ridge to the drain opening.

5. A centrifugal extractor for yarn packages, comprising a frame providing spaced bearings, a vertical shaft journalled in said bearings and projecting above the frame, and a holder having a bottom mounted on said shaft above its bearings and preventing access to the bearings and a cylindrical wall surrounding the upper portion of the shaft, said shaft containing an oil duct extending downwardly from its upper end and outwardly below the bottom of said holder to said bearings.

In testimony whereof I have hereunto set my hand.
